Absaroka-Beartooth Wilderness. Engelmann spruce-subalpine fir below treeline. Short but productive season due to extreme elevation. King boletes near timberline.

**Beartooth/Absaroka A-Tier Assessment** You're sitting in prime true morel territory right now—soil temps have been consistently above threshold for a week, moisture is locked in (0.28 VWC sustained), and the accelerating melt is pushing fresh water into the system exactly when you need it. The snowline positioning (8,230 ft south-facing) means the best elevations are opening up in real time. This is textbook morel conditions: you're in the window. The secondary tier species (chaga, spring kings, false morels) are marginal at current temps but will flip to high viability within 3–5 days as soil temps climb above 50°F. Don't sleep on false morels right now—they tolerate cooler soil than true morels and moisture is their primary demand, which you've got. Your limiting factor is desiccation risk, which is real: at high elevations with accelerating melt and thin snowpack (59% SWE), evaporation will spike hard once temps climb. That moisture window compresses fast. The next 48 hours are critical before the system dries out. Hunt south-facing slopes between 8,500–10,000 ft where snow is actively retreating—that interface zone is where morels fruit. Focus on aspen and cottonwood. **Hot tip:** Get above the snowline on south aspects tomorrow; the melt surge is happening now and morels pin within 36 hours of that moisture pulse.

Primordia readiness: Cold = mycelium dormant. Activating = soil warming, primordia building. Primed = 5+ sustained warm days at species threshold; fruiting imminent if moisture cooperates. Based on Schmidt 1983 / Mihail 2007.
